Any tag can be your key.
Peace works with virtually any 13.56 MHz NFC tag — scan it once and it becomes a physical switch for your focus. Here’s what people use, and how to set one up.
💡 You don’t need anything special. A hotel key card, an amiibo, or an NFC sticker you already own will work. The picks below are just easy, affordable options.

NFC stickers (NTAG215)
Thin, cheap, and stick anywhere — by your bed, on your desk, inside a book. Buy a roll and place a “focus key” in every room.
Shop NFC stickers →NFC cards & keychains
Wallet-sized cards and keyring fobs you can carry. Great for locking on the go, or handing a “study key” to a teen.
Shop cards & keychains →amiibo & collectibles
Already have amiibo figures or cards? They’re NFC too. Turn a favorite character into your bedtime wind-down key.
Browse amiibo →Epoxy & wood tags
Pretty, durable tags that look like décor instead of tech. Perfect for a nightstand or entryway bowl.
Shop décor tags →Hotel keys & transit cards
Many hotel keycards and access fobs are read-only NFC — perfect as a dedicated key you scan in the app. (Some transit cards are locked and may not read.)
No purchase neededTap-to-lock when closed
On writable tags (like blank NTAG stickers), Peace can write a launch link so a tap opens the app and toggles your lock — even when Peace isn’t open.
